Abstract

PROBLEM TO BE SOLVED: To allow regular lamination of plural parts cut from a sheet.SOLUTION: Parts on a lamination stand are laminated by the following method: a sheet material is cut by a cutting head on a cutting conveyer and the cut sheet material is carried out to the top of a carry-out table by the cutting conveyer; an extension roller for supporting an extension sheet goes towards the top of a lamination stand of the downstream side of the carry-out table from a retreat position of the carry-out table and by the speed difference of the extension roller and the carrying out speed of the cutting conveyer parts are divided per one part between the carry-out table and the extension sheet; and a rear end of the part on the extension sheet is separated from the tip end of the carry-out table by a predetermined distance or more from where the extension roller is retreated. Thereby, while preventing parts from entering into a lower part of the carry-out table, the parts are laminated on the lamination stand.

Description

  The present invention relates to cutting a sheet material into parts and laminating the cut parts.

  The applicant has developed a device that cuts a prepreg, which is a sheet of carbon fiber or glass fiber, and a thermosetting resin into parts, and stacks the cut parts. In such a cutting and laminating apparatus, it is necessary to separate parts from each other and stack them regularly. In particular, when an adhesive prepreg sheet is cut, the parts tend to stick to each other.

  Here is related prior art. In the cutting and laminating apparatus of Patent Document 1 (JP2010-13740A), an extension roller that reciprocates on the stacking base is provided, and the extension sheet is extended onto the stacking base by advancing the extension roller. Wind up with another roller. Then, when the fabric from the original fabric is placed on the stretch sheet and the stretch roller is advanced, the fabric is fed onto the stacking table. Next, when the extension roller is retracted, the dough loses its support by the extension sheet and descends onto the stacking table. In the middle of the descent, the dough is cut with a cutter. However, Patent Document 1 does not disclose that the cut parts are separated from each other and stacked. Patent Document 2 (JPH10-140469A) discloses that an endless belt is extended and retracted on a stacking table by an extension roller and another movable roller on the opposite side of the belt.

A step of laminating the parts on the stacking table so that the rear end of the parts on the extension sheet is not more than a predetermined length away from the front end of the carry-out table by retracting the extension roller so as not to enter below the carry-out table; And executing.

  In the present invention, the sheet material is cut on a cutting conveyor, transferred onto a carry-out table by the cutting conveyor, separated into parts by the speed difference between the extended sheet and the cutting conveyor, and transferred onto the extended sheet. The speed difference includes stopping the cutting conveyor. Then, the parts are stacked on the stacking table by retracting the extension roller from a position where the rear end of the parts on the extension sheet is separated from the front end of the carry-out table by a predetermined length or more. Here, the carry-out table has the stacking table side (extension sheet side) as the leading end and the cutting conveyor side as the trailing end. When the part descends from the extension sheet, the part descends along the extension roller and comes into contact with the stacking table at a position returning to the carry-out table side. However, in the present invention, the extension roller is moved backward from a position where the rear end of the part on the extension sheet is separated from the front end of the carry-out table by a predetermined length or more. Here, the predetermined length is, for example, 1 cm or more and 10 cm or less, and is equal to or longer than the distance to return to the carry-out table side when the parts are lowered onto the stacking table. For this reason, parts do not enter below the carry-out table. Further, the extension sheet driving mechanism composed of rollers or the like is located under the carry-out table, so that space is saved. Preferably, a motor or the like for driving the drive mechanism is also stored below the carry-out table. Note that the entire extension sheet and its driving mechanism are called a laminating apparatus. In this specification, the description relating to the cutting and laminating apparatus also applies to the cutting and laminating method. The object to be cut is arbitrary, but even an adhesive sheet material can reliably separate parts and can be laminated in a regular shape.

  Preferably, the cutting and laminating apparatus is configured to stop the cutting conveyor when the parts are completely moved from the carry-out table to the extended sheet. If the cutting conveyor is stopped after the parts are completely transferred onto the extension sheet and the extension sheet is advanced further, the parts on the extension sheet are pulled away from the carry-out table and at the same time separated from the next part on the carry-out table. Is done.

  More preferably, the cutting and laminating apparatus is configured to stop the cutting conveyor before the center of gravity of the next part to be moved onto the extension sheet moves from the carry-out table onto the extension sheet. The center of gravity of the part is known to the controller that controls the cutting conveyor, and can be obtained by image recognition or the like. In this case, since the part is cut obliquely, even if the tip of the part protrudes from the carry-out table, the next part does not fall onto the extension sheet.

  Further preferably, the cutting laminating apparatus is configured such that the controller controls the cutting unit so that the cutting conveyor stops in parallel with the withdrawal of the extension roller and the cutting head cuts at least one part of the sheet material. Yes. If it does in this way, cutting and lamination of parts can be performed simultaneously and a required time can be shortened. The entire process is repeated by cutting and stacking parts and separating parts.

  Preferably, the laminating / cutting device is configured to support the bottom surface of the extension sheet, a pair of left and right support roller gates that support and retract with the extension roller while supporting the support roller, and return and support while supporting the extension roller. And further comprising a gate for the extension roller and a connecting member for connecting the left and right support roller gates, and the support roller, the gate for the support roller and the connection member are disposed on the carry-out table side when viewed from the extension roller, The extension roller is configured to shift the position of the stack on the stacking table for each stack of a plurality of parts, and to form a rear stack on the near side as viewed from the carry-out table with respect to the stacked stack. It is comprised so that the advance position of may be controlled.

  In a preferred cutting and laminating method, a pair of left and right supports that are retracted together with the extension roller, supported on the bottom surface of the extension sheet by a support roller disposed on the carry-out table side when viewed from the extension roller, and connected by a connecting member. The roller is supported by the roller gate, and the controller shifts the position of the stack on the stacking base for each stack of a plurality of parts, and is closer to the transport table than the stacked stack. The advance position of the extension roller is controlled so that the rear stack is formed on the side.

  By providing the support roller on the carry-out table side when viewed from the extension roller, it is possible to prevent the extension sheet from loosening. Next, by connecting the left and right support roller gates with the connecting member, it is possible to prevent rattling of the left and right support roller gates that support the support roller. As shown in FIGS. 6 to 10, the connecting member is preferably a beam or the like disposed below the support roller. However, a rod-shaped connection member may be accommodated in the hollow portion of the support roller, and the left and right support roller gates may be connected. By forming the rear stack on the near side as viewed from the carry-out table with respect to the stacked stack, it is possible to prevent interference with the stack of cut parts even if the position of the connecting member or the support roller is low. In order to lower the position of the connecting member, etc., the support roller and the extension roller are arranged at a low position, and as a result, the distance at which the parts fall is shortened so that even small parts can be stacked regularly. effective.

  Examples for carrying out the invention are shown below.

  1 to 5 show the cutting and laminating apparatus 2 and the cutting and laminating method of the embodiment. As shown in FIG. 1, in the cutting and laminating apparatus 2, a cutting unit 4, a carry-out table 6, and a stacking unit 8 are arranged from the upstream side to the downstream side along the sheet material conveyance direction. And the stacking unit 8 are controlled. A cutting head 12 includes a cutting blade 14 such as a knife or a round blade, and a camera 16. The cutting head 12 moves in the y direction in FIG. 1 along the arm 18, and moves in the x direction in FIG. . The camera 16 detects the side edge of the sheet material, and detects the inclination of the sheet material from the conveying direction (x direction in FIG. 1). The camera 16 may be provided on a member other than the cutting head 12, and the inclination of the sheet material may be detected by a sensor other than the camera 16. A cutting conveyor 22 includes a bristle sheet 23 and a power roller 24 that feeds the bristle sheet 23. The cutting blade 14 cuts a sheet material on the bristle sheet.

  The carry-out table 6 has a table-like upper surface, and the lower part is assigned to a space for accommodating the mechanism of the laminated unit 8, particularly the drive mechanism of the elongated sheet 28. The parts cut from the sheet material by the cutting unit 4 are carried out onto the carry-out table 6 by the cutting conveyor 22 without being separated, and due to the speed difference between the cutting conveyor 22 and the extension sheet 28 of the stacking device 26 of the stacking unit 8. They are separated from each other and transferred one by one onto the extension sheet 28 of the laminating apparatus 26. In the laminating device 26, the front end of the extension sheet 28 is fixed to the extension roller 30, and the extension roller 30 is supported by, for example, a pair of carriages 32 and 32, and reciprocates along the rail 34 and the x direction in FIG. To do. When the extension roller 30 moves in the x direction (hereinafter, this operation is referred to as “advance”), the extension sheet 28 is extended onto the stacking table 40. When the extension roller 30 moves in the direction opposite to the x direction (hereinafter, this operation is referred to as “retreat”), the extension roller 30 rotates to wind up the extension sheet 28. A support roller 35 moves in the same direction as the extension roller 30 along the rail 34, and supports the extension sheet 28 from below to prevent bending. The support roller 35 may be pushed or pulled by the extension roller 30 or moved by meshing with the extension sheet 28, and the support roller 35 may not be provided. Reference numeral 36 denotes a base roller, reference numeral 38 denotes an intermediate roller, and the rollers 36 and 38 are fixed in position. The rollers 36 and 38 are provided at the lower part of the carry-out table 6. The rollers 30 and 36 are power rollers that can freely take up the elongated sheet, and are driven by motors M2 and M3 having brakes, for example, and the intermediate roller 38 and the support roller 35 are driven rollers. The parts lowered from the elongated sheet 28 are regularly stacked on the stacking table 40. The motor M3 is provided with a brake in order to apply tension to the extension sheet 28.

  The sheet material to be cut is, for example, a prepreg made of carbon fiber or glass fiber and an uncured thermosetting resin, and the prepreg is adhesive. In addition to the prepreg, a coating film or the like coated on a base film can be cut as an adhesive sheet material. Further, not only the adhesive sheet material, but also the sheet laminating apparatus 2 can be used when the sheet material is cut into parts without being laminated and the parts are laminated after the cutting. In the cut lamination, it is important to regularly stack the parts on the stacking table 40, and particularly when the parts are lowered from the extending sheet 28, the parts are brought into the carry-out table 6 due to the height difference between the extending sheet 28 and the stacking table 40. It is important not to be lowered to the bottom. In the case where the object to be cut is an adhesive sheet material, it is also important to separate the cut parts from each other and to prevent the parts from being caught on the carry-out table 6.

  FIG. 2 shows a control system of the lamination cutting apparatus, and M1 to M8 are motors. In the laminated unit controller 42, the extension roller traveling drive 44 controls the motor M1 to control the extension roller 30 to move forward and backward. The extension roller winding drive 45 controls the motor M2 to control the winding of the extension sheet 28 by the extension roller 30. Further, the drives 44 and 45 prevent the extension sheet 30 from moving in the horizontal direction by retracting the extension roller 30 and winding the extension sheet 28 by the extension roller 30 at a constant speed. The base roller take-up drive 46 controls the motor M3 to control the take-up of the elongated sheet 28 by the base roller 36. The cutting conveyor drive 50 controls the cutting conveyor 22 by controlling the motor M4.

  In the cutting head controller 52, the cutting head travel drive 54 controls the motors M5 and M6 provided on the carriages 20 and 20 to move the cutting head 12 back and forth in the x direction, and controls the motor M7 to cut the cutting head. 12 is moved in the y direction. The cutting blade drive 56 controls the motor M8 to move the cutting blade 14 up and down or rotate. However, in the case of a prepreg, the cutting blade 14 can be fixed and pushed off, and in this case, the cutting blade drive 56 is unnecessary. The camera drive 58 causes the camera 16 to photograph the side edge of the sheet material, and obtains the inclination of the side edge of the sheet material from the x direction from the obtained image. The controller 10 controls the drives 44 to 58 and the like to cause the cutting and laminating apparatus 2 to execute a predetermined cutting and laminating operation.

  FIG. 3 shows the cutting lamination in the embodiment, and the cutting lamination is executed under the control of the controller 10. In step 1, the extension sheet 28 starts to be extended, and in synchronization with this, that is, at the same conveying speed, the cutting conveyor 22 starts to carry out the cut parts (step 2). Further, the cutting head 12 is returned to the origin while the extension sheet 28 is extended (step 3). The position of the cut part, in particular, the position of the center of gravity G of the part is known to the controller 10 or the cutting conveyor drive 50, and the current part is the carry-out table on condition that the center of gravity G of the next part does not come out of the carry-out table 6. The cutting conveyor 22 is operated until it completely moves from 6 onto the elongated sheet 28 (step 4). If the center of gravity G of the next part may come out of the carry-out table 6 before the current part finishes moving on the extension sheet 28, the cutting conveyor 22 is stopped before the center of gravity G comes out of the carry-out table 6. The current part is a part that is then lowered onto the stacking table 40 via the extension sheet 28.

  Even after the cutting conveyor 22 stops, the extension sheet 28 continues to be extended (step 5). When the rear end of the current part advances from the carry-out table by a predetermined length of 1 cm to 10 cm, preferably 3 cm to 10 cm in the x direction, the extension roller 30 starts to return, and the current part is placed on the stacking table 40. Lower and stack. At this time, the extension sheet 28 is wound around the extension roller 30 at the same speed as the retraction speed of the extension roller 30 so that the extension sheet 28 is wound up without moving in the x direction (step 6). As a result, the parts are moved down and stacked on the stacking table 40 while hardly moving in the x direction. When the extension roller 30 is retracted to the lower side of the carry-out table 6, the winding of the extension sheet is stopped and the extension sheet 28 is taken up by the base roller 36 (step 7).

  During the execution of steps 6 and 7, the cutting conveyor 22 is in a stopped state, and, for example, one part is newly cut by the cutting head 12. The cutting head 12 moves from the origin to the cutting start position. For example, the side edge of the sheet material is photographed by the camera 16 at the same time to obtain the inclination thereof, and the cutting line is corrected (step 8). In step 9, the parts are cut. In FIG. 3, the cutting head 12 is returned to the origin in parallel with Steps 1 and 2, but the cutting head 12 may be returned to the origin in parallel with Step 7.

  4 and 5 schematically show the cut lamination, the states a) to d) are the same as those in FIGS. 4 and 5, and S is a long sheet material such as a carbon prepreg. P1 is the current part, P2 is the next part, G is the center of gravity, and P3 is the next part. In a), the cutting head 12 is returning toward the origin, for example, and both the cutting conveyor 22 and the extension roller 30 move at the same speed, and the current part P1 is being transferred onto the extension sheet 28. Preferably, the cutting conveyor 22 is operated until the current part P1 is completely moved onto the extension sheet 28, in other words, the rear end thereof leaves the carry-out table 6, during which the center of gravity G of the next part is removed from the carry-out table 6. If there is a risk of protruding, the cutting conveyor 22 is stopped without waiting for the current part P1 to completely move onto the elongated sheet 28.

  FIG. 4 and FIG. 5 b) show a state where the current part P1 and the next part P2 are separated, the current part P1 is completely moved onto the elongated sheet 28, and the cutting conveyor 22 is stopped. 4 and 5, the cutting head 12 is returned to the origin F (the most advanced position of the part). Even if the extension roller 30 is moved at a relatively high speed and the cutting conveyor 22 is moved at a relatively low speed from the state a), the current part P1 and the next part P2 can be separated by the state b). When the extension roller 30 is further advanced from FIG. 4 and FIG. 5 b), the distance between the current part P1 and the next part P2 increases, and at a position suitable for lowering the current part P1 onto the stacking table 40. To reach. This position is such that the rear end of the current part P1 advances a predetermined length from the front end of the carry-out table 6 and is lowered onto the stacking table 40 so that the rear end of the current part P1 is not hidden below the carry-out table 6. is there.

  When reaching a position suitable for lowering the current part P1 onto the stacking table 40, the extension roller 30 is retracted while winding the extension sheet 28. When the extension roller 30 is retracted, the current part P1 should be lowered straight, but actually the current part P1 is lowered so as to move slightly toward the carry-out table 6 side. This is because the current part P1 descends onto the laminate 60 so as to descend along the extension roller 30. Therefore, when the rear end of the current part P1 is separated from the front end of the carry-out table 6 by a predetermined length of about 1 cm to 10 cm, for example, in the x direction in FIG. Then, the extension roller 30 is rotated at the same speed as the extension roller 30 returns to the horizontal direction, and the extension sheet 28 is wound up. When viewed from the current part P1 side, the extension sheet 30 is wound around the extension roller 30 without moving horizontally. Further, when the rotation speed of the extension roller 30 is made constant, the diameter of the sheet is increased by winding, so that the winding speed is increased. Therefore, for example, when the return speed of the extension roller 30 is set to a constant speed, the winding speed (rotational speed) of the extension roller 30 is reduced according to the diameter of the wound sheet. FIG. 4 and FIG. 5 c) show a state in which the extension roller 30 is returning.

  When the return of the extension roller 30 is completed, the extension sheet 28 is taken up from the extension roller 30 by the base roller 36 (d in FIGS. 4 and 5). 4 and 5, the cutting conveyor 22 is stopped, and the cutting head 12 cuts parts. When the cutting for one part and the winding by the base roller 36 are completed, the unloading by the cutting conveyor 22 and the advancement of the extension roller 30 are resumed, and the state returns to the state of a) of FIGS.

The embodiment has the following characteristics.
1) The parts are separated by the speed difference between the cutting conveyor 22 and the extension sheet 28. As a result, even sticky parts can be reliably separated.
2) Continue conveying by the cutting conveyor 22 until the current part P1 is completely moved onto the elongated sheet 28. Next, the cutting conveyor 22 is stopped and the extension sheet 28 continues to advance. Then, the current part P1 can be separated from the carry-out table 6 at the same time as the part P1 is separated from the part P2.
3) Since the cutting conveyor 22 is stopped before the center of gravity G of the next part P2 comes out of the carry-out table 6, the next part P2 does not fall on the extension sheet 28 carelessly.
4) When the rear end of the current part P1 advances from the front end of the carry-out table 6 by a predetermined length or more, preferably by a predetermined length, the extension roller 30 starts to retract, so the current part P1 descends along the extension roller 30. Even so, the rear end of the current part P1 does not enter below the carry-out table 6. Therefore, the laminate 60 can be easily taken out.
5) Since the extension roller 30 is retracted and the extension sheet 28 is wound at a constant speed, no horizontal force is applied to the current part P1.
6) Space is saved because there is only one base roller 36, and when the extension roller 30 is advanced, there is no need to feed out the extension sheet synchronously from the pair of base rollers. Furthermore, since it is easy to apply a large tension to the elongated sheet 28 at the time of elongation, the deflection can be reduced.
7) Deflection of the elongated sheet 28 can be reduced by the support roller 35.
8) Since the cutting head is operated in parallel with the operations of c) and d) of FIGS. 4 and 5, the processing time per part is short.

Optimum Embodiment FIGS. 6 to 8 show that the beam 72 prevents the support roller gates 70a and 70b that support the support roller 35 from being rattled, and prevents interference between the stacks 74 to 78 on the stacking table 40 and the beam 72. An optimal embodiment to prevent is shown. The embodiment is the same as the embodiment shown in FIGS. 6 and 7 is a new stacking unit. The stacked unit 8 shown in FIGS. 1 to 5 is provided with beams 72 and 73 and a sensor 68, and an extension roller gate 66 for supporting the extension roller 30. The movement is changed to traction by the toothed belt 74 instead of self-propelled on the rail. A toothed belt 64 is disposed along the base 62 of the laminated unit 9 and the extension roller gate 66 that supports the extension roller 30 is moved in and out in the left-right direction in FIG. The stacking table 40 is supported on the base 62, and for example, a pair of support rollers 35 and 35 are supported by support roller gates 70 a and 70 b along the longitudinal direction of the stacking table 40. The support roller gates 70 a and 70 b are moved out along a rail 71 provided along the stacking table 40. Further, the extension roller gate 66 is provided with a sensor 68 for detecting a part that is not completely cut from the sheet material and remains on the extension sheet 28. This detection is performed by, for example, detecting a part that hangs down from the extension roller 30 by the sensor 68 when the extension roller 30 is retracted. H2 is a height level at which the sensor 68 detects uncut parts.

  In the support roller gates 70a and 70b, a beam 72 is provided below the support roller 35, and the left and right support roller gates 70a and 70a are connected by the beam 72 as shown in FIG. Similarly, a pair of extension roller gates 66 are provided on the left and right of the stacking table 40, and the left and right extension roller gates 66, 66 are connected to each other by a beam 73 provided on the extension roller 30. The reason why the beams 72 and 73 are necessary is that if the left and right support roller gates 70a, 70b, and 66 are connected only by the rollers 35 and 30, rigidity is insufficient and the gates 70a, 70b, and 66 may be rattled. . Therefore, the left and right gates 70a, 70b, 66 are connected by beams 72, 73, and the structure composed of the support roller gates 70a, 70b and the support roller 35, and the extension roller gate 66 and the extension roller 30 are combined. Increase the rigidity of the structure. The support roller 35, the support roller gates 70 a and 70 b, and the beam 72 are arranged on the carry-out table 6 side as viewed from the extension roller 30, and these move in and out in conjunction with the extension roller 30 and the extension roller gate 66.

  The support roller gates 70a and 70b are taken out and withdrawn by the extension roller gate 66 and the like, and the entrainment is released by an entrainment release member (not shown) such as protrusions provided at two locations of the rail 71, for example. That is, when the extension roller gate 66 moves backward to the right in FIG. 6, the extension roller gate 66 and the left support roller gate 70a are engaged with each other, for example, and then the left support roller gate 70a and the right support roller gate 70a are engaged. The support roller gate 70b is engaged, for example, to be accompanied. When the extension roller gate 66 advances to the left in FIG. 6, the first entrainment release member releases the entrainment due to the engagement between the support roller gates 70a and 70b, and the next entrainment release member releases the gate 66, The entrainment by the engagement between 70a etc. is cancelled | released. The support roller gates 70a and 70b may be self-propelled without being accompanied. H1 is the bottom surface level of the beam 72. Within the range in which the support roller 35 advances, the cut parts are stacked at a position lower than this height.

  8 to 10 show a stack of cut parts, and there is a carry-out table 6 (not shown) on the right side of the figure. 74 to 80 are a stack of cut parts, each consisting of a plurality of parts. As shown in FIG. 8, when the position is shifted closer to the carry-out table for each stack, interference between the beam 72 and the cut parts can be avoided even if the total number of cut sheets is the same as in FIG. For example, in FIG. 7, the most advanced position of the beam 72 is at a position off the first stack 74 (position near the carry-out table), and the bottom level H1 of the beam is higher than the total thickness of the two stacks 76 and 78. Therefore, interference with the stacks 76 and 78 can be avoided. The thickness of the stacks 74 to 80 is obtained by adding an element such as warp to the thickness of the part × the number of stacked layers due to warpage of the cut parts.

  The stacks 74, 76, and 78 need not be sequentially shifted to the carry-out table 6 side. For example, as shown in FIG.

  FIG. 10 shows a stack 80 in which all the parts are stacked at the same position without shifting each of the plurality of parts. When the number of stacked layers is increased, interference between the stack 80 and the beam 72 occurs. If the height of the beam 72, the support roller 35, the extension roller 30, etc. is increased, it becomes difficult to regularly stack small parts.

  In order to form the stacks 74 to 78 by shifting the positions as shown in FIGS. 8 and 9, the most advanced position of the extension roller 30 is shifted for each stack by the controller 10 of FIG. 1. Note that the number of stacks is not limited to 3, but is 2 or more, for example, 10 or less. In addition, when stacks 74 to 78 are formed for each of a plurality of parts, it is easy to carry out the cut parts manually. As shown in FIGS. 8 and 9, particularly FIG. 8, by shifting the position of each of the stacks 74 to 78 toward the carry-out table 6, a large number of parts can be stacked while avoiding interference with the beam 72.

  The structure itself of the laminating apparatus 26 is arbitrary, and for example, the mechanism of Patent Document 1 may be used. For example, another power roller may be provided on the side opposite to the base roller 36 when viewed from the extension roller 30, and the extension sheet 28 may be wound up by another power roller instead of the extension roller 30. Further, as in Patent Document 2, an extension sheet may be wound endlessly, the extension roller 30 may be disposed at one end, and another movable roller (not illustrated) may be disposed at the other end. When the movable roller and the extension roller 30 are horizontally moved in opposite directions, the extension sheet 28 advances as the extension roller 30 advances, and the extension sheet 28 moves backward as the extension roller 30 moves backward. Also in this case, the main part of the drive mechanism for the elongated sheet is accommodated below the carry-out table. In the embodiment, a parallelogram-shaped part is shown, but the shape of the part is arbitrary such as a rectangle, a square, and other shapes.
